Katy Perry has promised her new songs will be more mature - because she now knows how to "handle" boys.

The 'I Kissed a Girl' singer - who is currently dating British comedian Russell Brand - insists her follow-up material to debut album 'One of the Boys' will be influenced by her romantic experiences.

She said: "My new songs are a little bit more mature. I know how to handle boys now.

"Actually, I don't even mess with boys anymore, I mess with men. It's different because on 'One of the Boys' I was, like, 17 to 23 and some of those songs, like half the record, I wrote when I was 19 - and that's such a different place than you are when you're 25."
